I ran into a showstopper with mapgen4. It unpredictably "freezes" in the sense that inputs have no effect, even though both the map generation and rendering are running. I'm taking a break from that for ProcGen 2018 - 9 days to work on a procedural generation project.

I decided to play with procedural map generation on a sphere. I've long wanted to try generating entire planets instead of flat maps. See this project and this project to get an idea of what I'm wanting to learn how to do.

I don't want to spend a lot of time on it, but I think a week would be a good amount of time. The rough plan:

The core map algorithms in mapgen4 run on a dual mesh, which means they are not restricted to run on a flat grid. I am optimistic that most of them will run on a sphere. The main exception is wind+rain, which I'll either drop or adapt. The rendering algorithms in mapgen4 won't run easily on a sphere. The oblique projection is designed to match hand drawn paper maps; the outlines work by rendering a flat map to a texture, and probably won't work on a sphere. That's ok. It's a one week miniproject to try something different, and I will be happy if I get half of it working.
